Notis

Check upcoming base fees against your deadline

Put the next five blocks of fee predictions beside the campaign deadline before deciding when to act.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Get Base Fee Estimates

Retrieves real-time estimates of Ethereum's base and transaction fees for the next five blocks.

Why this helps

A deadline alone does not show whether upcoming base fees are likely to fit the transaction plan.

  • See 99% and 50% confidence estimates for upcoming blocks.
  • Compare fee predictions with a deadline included in the request.
  • Get one focused summary instead of manually checking estimates.

Setup

Build it in a few focused steps.

  • 1Connect ActiveTrail and Blocknative once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it.
  • 3Tell Notis to retrieve the next five blocks of base fee estimates and summarize them against the campaign deadline provided in the request.
  • 4Choose a webhook trigger and select where run reports should go.
  • 5Send one real deadline example and review the resulting estimates and summary.

Questions about this workflow

What fee information does this action return?

Does it determine whether a campaign should send?
